Was she dropped on her head recently? If she's trying to follow Sinead O'Connor's lead, I don't think Sinead's career got any kind of a boost from her SNL antics.
And, in fairness, Sinead O'Connor wasn't singing for the pope or selling her wares via religious marketers. This girl don't know which side her bread is buttered on.
I remember hearing that Sinead was booed off stage at one of her concerts. She desreved it.
